Elements Massage in Boulder, Colo., recently surveyed its clients and asked if they wanted to have appointments confirmed 24 hours in advance via e-mail, phone, or text. Over one-third of the clients requested a text message. The salon’s solution? TextUs.Biz, an app for PC, Mac, or iPad that allows the salon to use its existing landline telephone number to text messages back and forth with customers. TextUs.Biz allows you to manage multiple conversations at the same time using your current business landline to send and receive text messages directly between your computer and any phone.
